British runner Mo Farah has become only the second man in history to complete an Olympic and world 'double-double' in the distance events.
The dual Olympic champion held on in a thrilling finish at the world athletics championships in Moscow to add the 5,000 metres title to the 10,000 metre gold he won on Sunday.
Farah joins Ethiopian legend Kenenisa Bekele as the only male athlete to win the men's 5000-10,000m double at the same world championships.
New Zealand runner Zane Robertson was second to last in the final.
Jamaica's Shelly-Ann Fraser-Pryce completed a brilliant world championship sprint double as she added the 200 metres gold to the 100 title, clocking a winning time of 22.17 seconds and becoming the first woman since East Germany's Katrin Krabbe in 1991 to do the sprint double at world level.
